Estimate the roots of the equation by graphing. Round to the nearest tenth and write in set form, such as {-1.2,3.4}. x2 - 6= 0 Estimate the zeros of the equation by graphing. Round your solutions to the nearest tenth and write them in set form, such as {-1.2,3.4}. x2 - 12 = 0

    |dw:1334177669703:dw| they are both curves of x^2 shifted 6 units and 12 units downwards, repectively now for the zeroes, x^2-6=0 and similarly x^2 -12 =0 so find x for each equation, and present them as elements of the sets (two different questions)

    the value of x's at those points is your solution.

    you should plot points until your graph look like this http://www4c.wolframalpha.com/Calculate/MSP/MSP39321a134388b6gfd2fc00001879gf5182cd4735?MSPStoreType=image/gif&s=48&w=296&h=300&cdf=RangeControl and at those points i showed arrow, you will have your solutions.
